Source for ceramic h4 plugs?

Ive been doing some electrical system repairs and part of the work involved improving my headlight relay setup. I installed a nice Hella relay panel and replaced the wiring to the headlights with nice 10 gauge wires.

I read somewhere that replacing the h4 plugs with a ceramic version is a good idea (I have the 80/100 watt bulbs).

I found some ceramic plugs on Amazon, but they have wires exiting directly out the back, while the factory plugs have wires that exit at a 90 degree angle. I feel that may interfere with the headlight, as there's not much space in the bucket.

Anyone have any experience with this or an alternative source?

This isn't a Porsche plug, but this shows how the factory plugs have the wires exit:



This is what the Amazon plugs look like:

First, Headlight connectors

Second, the straight plugs fit just fine, I and many others have them in our cars. Same setup, 80/100 bulbs, generic ceramic plugs, upgraded wiring, stock buckets.

Mine came from Daniel Stern Lighting with his kit, maybe he would sell them to you. They accept the stripped wire end directly with little spring loaded connectors from the side as I remember, no added connections. Not looked in a few years.

Napa sells a nice Bakelite connector. I haven't had any issues using them on high-wattage bulbs.

I found male/femal adapters on eBay that plug right into your existing plug.
